TDA30 won't release lines after divert

TDA30 won't release lines after divert

Have just set up an external divert on a TDA30 which is working, but once the call is finished the system is not releasing the lines. It's as if the system has not detected the calls have finished.

Just did a test and even after unplugging the lines and reconnecting them, the system still sees them as in use. After 10 mins I had to power cycle the machine just to get the use of the lines back.

TDA30 with TVM50, analoge POTS lines.

Any ideas? I'm pulling my hair out!
Many thanks

RE: TDA30 won't release lines after divert

If you don’t have cpc signal on the analogue line it won’t know the call has ended so will not clear down. You could set co to co timer to lower than 10 minutes so the call is disconnected after a few minutes

We would normally only do this option with isdn
